Title: Method and apparatus for fabricating grid structures for cathode ray tubes
IPC: H01J19/00
Filed: 1953-12-22
Abstract: 757,811. Colour television electrodes. CHROMATIC TELEVISION LABORATORIES, Inc. Dec. 22, 1953 [Jan. 14, 1953], No. 35586/53. Class 39 (1). [Also in Group XXII] Grid electrodes are made by temporarily securing a plurality of closely spaced wires in parallel relationship or winding a continuous wire to form a plurality of closely spaced turns before securing, positioning the so-formed set of anchored wires at the desired separation distance, tautening the wires and positioning a final anchoring frame adjacent to the taut wires and securing them thereto, e.g. by means of cement. The grids are wound on a drum 23 with two opposed slots 27 wide enough each to receive two holders 31 faced at 33 with rubber or rubberized fabric and wedging cams or shims. The wire is fed through a laterally moving guide 17 as the drum rotates and, after the winding operation, is secured to the holders by clamp bars 35 and bolts 43. The wires 11 are severed along line 51, the shims removed, and the grids in the holders 31 transferred to a bed-plate 63 (Fig. 1). One holder 31 is clamped in blocks 65, 67 and the wires are laid across guide slots in the bar 69, 69<SP>1</SP> and over the frame 75 to which the grid is to be secured, the other holder 31 being either allowed to overhang the bed-plate or spring-loaded. There may be insulating material between the wires 11 and the frame 75. With the grid wires taut and aligned across the frame 77, cement which may be of insulating material is applied at 83 having an expansion co-efficient close to those of the grid wire and the frame. After removing the holders 31, the grid assembly is baked to harden the cement, the grid wires being of material with an expansion co-efficient greater than the support frame to prevent fracture at this stage. Stainless steels of different expansion co-efficients are instanced. Alternatively the upturned edges of frame 77 may be of glass and a glass core is laid across the wires at that point, and the whole is fused by heating. Welding, hard soldering, brazing and other techniques may be used to secure the wires to the frames. Instead of winding a single wire, a plurality of wires may be drawn from spools through aligned openings and clamped at points corresponding to the desired length of the grid, a third clamp being applied to the wires which are then cut between the second and third clamp, permitting the production of a succession of grids. The distances apart of the positioning slots may be progressively different if a grid of this form is required, as in cathoderay tubes. Specifications 721,523, 757,787 and 757,879 are referred to.

Title: Improvements relating to the melting and refining of magnesium and its alloys
IPC: C22B26/22
Filed: 1936-12-31
Abstract: Magnesium or its alloys are refined or melted by contacting the molten metal with a flux and subsequently allowing the mixture to settle out of access of air, the flux comprising a mixture of the chlorides of magnesium, an alkaline earth metal, and an alkali metal, having a specific gravity above that of the molten metal and a wetting capacity such that the molten metal swims on the flux and with gentle movement can be covered with a film thereof which endures for only a short time after the mixture has resumed a condition of rest.  The flux may comprise 15-40 per cent of magnesium chloride, 5-20 per cent of calcium chloride, 5-20 per cent of barium chloride, 0-10 per cent of sodium chloride, 0-5 per cent of calcium fluoride, and 0-5 per cent of magnesium fluoride, with the remainder potassium chloride in amount always greater than 40 per cent.  In addition, fluorides of alkali-earth metals, double fluorides of aluminium and the alkali-earth metals, boracic acid, and borax may be present.  In the case of refining, the metal may be melted under a known flux and transferred to a vessel where it is gently agitated or vigorously stirred with the flux.  In melting, the metal may be added little by little to a heated crucible to which the flux is added from time to time, or it may be melted in a large bath of flux.  In order subsequently to purify the molten metal, portions thereof are withdrawn and allowed to stand.  Attack by air is prevented by the use of a protective flux or atmosphere.  Specification 346,271 is referred to.

Patent GB-396690-A (GB)
Title: Treatment of sulphide ores
IPC: C22B15/06
Filed: 1931-12-29
Abstract: <PICT:0396690/III/1> Complex sulphide ore containing iron is subjected to an intensive oxidation, thereby removing the bulk of the sulphur and forming a molten product of the resulting oxidized ore in which the major part of the iron is present as magnetite.  The ore contains sufficient natural fuel to insure fusion of the product without the fluxing assistance of silica.  Ores deficient in fuel value are subjected to a preliminary concentration, or blended with ore of higher sulphide content.  Extraneous fuel may also be used. The molten oxidized product is then subjected to a selective reduction by a gas or atomized agent blown through the melt, or by a solid reducing agent mixed with the melt by means of a gas blown therethrough.  One form of apparatus for carrying out the oxidation and reduction is a tilting furnace or barrel converter having the bottom section in two parts 12, 13, one substantially flat and the other arched.  The crushed ore, if necessary after separation of dust, is fed alone into the furnace and melted by burners 23, or it may be charged on top of a small residual quantity of molten product from a previous operation.  An oxidizing gas, such as preheated air, is blown from tuyeres 14 through the molten mass, crushed ore being charged at about the same rate as that at which the heat developed melts the oxidized ore.  Fluxes such as lime, fluorspar, &c., that are required in subsequent operations are also charged.  Sulphur, and other volatile constituents such as lead, zinc, cadmium, pass off in the gaseous products through an exit opposite the burners 23, and the oxidation is continued until practically all the sulphur is eliminated.  The molten oxidized product may be transferred into another furnace for the selective reduction, or the same furnace may now be turned to bring the tuyeres 14 above the level of the melt. Preheated air or other gas is blown from auxiliary tuyeres in the section 13, through the melt mixed with coke, and air or other combustion-supporting gas is introduced above the melt through the tuyeres 14 to maintain a neutral or slightly reducing atmosphere. The reducing treatment produces gases containing a further part of the volatile constituents, a ferrous oxide product or slag, and a product such as impure copper or copper matte which separates by gravity from the iron oxide slag.  Fluxes may be added to lower the viscosity and fusion temperature of the iron oxide slag.  The gaseous products of the oxidizing and reducing operations are conducted to waste heat boilers, heat interchange apparatus to preheat the gases used in the operations, and to a bag-house or fume-collecting apparatus.  The fume product is treated for the recovery of the metallic constituents.  The gas exiting from the fume collector may be treated directly for the recovery of sulphur, or sulphuric acid, or the sulphur dioxide content of the gas may be first concentrated thereby permitting the production of marketable nitrogen.

Title: Improvements in and relating to a mechanism for automatically decreasing the number of loops in flat type knitting machines
IPC: D04B7/04
Filed: 1934-12-14
Abstract: 448,795. Knitting-machines. IMON, S., 76, Kamikakuda, Komeno-cho, Naka-ku, Nagoya, Japan. Dec. 14, 1934, No. 35958. Convention date, Dec. 28, 1933. [Class 74 (ii)] Narrowing in a flat-type knitting-machine is carried out by means which brings the tip of a transfer needle beneath the open latch of a .knitting needle, advances them together, retracts the knitting needle alone, shifts the knitting needles laterally one needle space, and advances the next knitting needle to take the loop from the transfer needle, which is then retracted. Cams A and B respectively advance. and retract the knitting needles, cam C advances and retracts the transfer needles, cam D controls the base 36 carrying the transfer needles, and cam E operates a threaded shaft 58 to shift the knitting needle bed 65 laterally. Cams A and B operate, through rods A<1>,B<1>, concentric shafts 67, 68, and racks 75, 76. Cam C operates, through rod C<1>, a gear 49 fixed to a shaft 50 journalled in the base 36, an intermediate gear 51, and a rack 39<1>. Cam D works a bell-crank lever 31 which moves the base 36, through a link 37. Cam E rotates the shaft 58 through a rod E<1> and pawl-and-ratchet mechanism. As a shaft 3, geared to the main shaft 2, rotates, a rocking lever 10 is actuated through links 9, 8, to reciprocate the usual needle actuating carriage 35. At the same time, an eccentric disc 5 intermittently drives a pattern belt 15. A feeler 14 thereon lifts a lever 18 and so, through associated mechanism, causes the rotation of a shaft 22 carrying the cams, one revolution. As the shaft 22 rotates, the cam D moves the base 36 to decreasing position. Meanwhile cam A has advanced the knitting needle 34 which is to be eliminated. The transfer needle 46 is next advanced by cam C, and its tip comes beneath the opened latch of the knitting needle. Both needles now advance together, the stitch being engaged by the transfer needle. The knitting needle is further advanced to free the stitch entirely from the latch, and then retracted. The needle bed 65 is then moved laterally one needle interval, by cam E, and the next needle is advanced to take the loop from the transfer needle, its latch being opened by a brush 47, and the transfer needle is retracted..
